IMPROVEMENT IN MACHINES FOR DRESSING HEADS T0 BARRELS.

Specieation forming part of Letters Patent No. 43,933, dated August 23, 1864; antedated August 16, 1864.

To (LZZ whom it may concer'm Be it known that I, WILLIAM TRAPP, of Elmira, county of lGhemung, and State of New York, have invented new and useful Improvements in Barrel-Head-Dressing Machines for Cutting and Planin g the Head-Pieces; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of the bed-plate otthe endless chain; also, the arrangement of the four cutting-knives, as fastened on each side of the mandrel also, the arrangement of the planing-knife, as located in relation to the cutters.

To (nable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

Figure 1 represents a side elevation of the machine; Fig. 2, a top view; Fig. 3, a side view of the endless chain with its bed-plates;

Fig. 4, the mandrel with thefourcutting-knives.

attached; Fig. 5, an end view of the mandrel with its four knives.

A represents the square wooden frame which supports the devices of the machine; I3, the table in front, with a circular saw, C, at one side.

l) is an upper sill at the top ot' the frame, to which the cutters or knives E, springroller G, elliptic spring H, and planing` knife J are attached and operate. (Seen at Fig. 2.) Between the sill D and top of frame A are wedges K, for the purpose of raising or leveling the knives to their proper height to regu late the cutting and planing operation by loosening or tightening the screws K2. The four knives E are long and flat, and are fastened rmly by screwbolts to the square mandrel or shaft L-one on each side of the mandrel-and extend half the length of the mandrel, which allows the knives to work more rapidly and requires less power than it' each knife E extended across the whole length of the mandrel L. The half-elliptic spring H holds the barrel head-piece (while being cut and planed) down to the bed-plate. The planing-knife J is located back of the knives E, extends across the machine the same width ot' the mandrel L, and is firmly fastened to the sill D, is regulated by set-screws M, and

inclines with its planingedge toward the cutters E. The spring-roller G extends across the machine the same width of the mandrel and guides and holds the piece to its bedplate, so that the piece may pass regularly under the cutters E.

The hinged-endless `chain N revolves on the drum-wheels P, and between which hinge -or joint R is a bed, S, constructed so as to receive one piece of heading, and has an iron or metal plate, T, fastened on top and projecting in front, having notches U at each end and a few in the center, so as to hold firmly and carry the piece of heading to be dressed. Each bed S is incline-shaped, so as to forni apiece of heading with a thick and thin edge. An opening', V, is left between every third bed S, so as to place therein a piece of wood, called a middle piece i of a head, and form both edges the same thickness of the thick edge of the tapered piece.

The piece of head being placed upon the bed S (or in the opening V for dressing the middle piece).is carried under the springroller G to the knives or revolving cutters E, which cut the top face of the piece level, when the planing-knife J shaves, planes, and smooths as the piece passes under it, throwing cti' the shaving ih a roll over the plane J, thence the piece is carried and dropped down at the rear end of the machine.

The gearing of the machine is put in operation by the driving-pulley No. 1, which is connected by a strap to the feed-wheel i', which drives the pinion 3 and operates the spur-l wheel 4, which drives the pinion 5, and operates the endless-chain spur-wheel 6, that is attached to one of the drums l). A strap connects pulleys 7 and 8, which gives motion to the circular saw C.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The shape and construction of the bedplate T, attached to the endless chain N, as herein described, and for the purposes set forth.

2. The combination ot the revolving cutter and planing-knife with the feeding-apron, when they are constructed and arranged substantially as described. A
